SPECIFICATION forming part of Letters Patent No. 311,459, dated J'anlary 27, 1885.

Application tiled December 29, 1883. (No model.)

To all whom t may concern.-

Be it known that I, ZEBULoN Davis, of Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Vapor-Burners; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it pertains to make anduse it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates .to an improvelnent in vapor-burners; and it consists in, irst, the combination, in a vapor-burner, of an endwise-moving valve, a pivoted lever for moving the valve, and 'a support or fulcrum for the lever,which projects down from theburner and supports the lever between its outer free end and its point of connection with the needle-valve; second, the combination, in a vapor-burner, of an endWise-moving valve, a pivoted lever for moving the valve,and a support for the lever, the support being formed as a part of the drip-cup and adapted to move concentrically to the needlavalve; third, the combination of the partially-rotating supplypipe having one or more vapor-burners connected thereto, the endwise-moving needles, the pivoted levers, and the endwisemoving rod provided With suitable inclines; fourth, in the arrangement and combination of parts, which will be more fully described hereinafter.

Figure 1 is an end elevation of a vapor-stove embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a detail view of the burner. Fig. 4 is an enlarged detail view of one of the operating-levers and its extinguishing mechanism. Fig. 5 is an enlarged detail view of the burner and the operating lever.

A represents the frame; B, the tank, and C the supply-pipe leading therefrom. This pipe is journaled in the frame, and is made to partially revolve when the tank is turned to one side for the purpose of being filled, as shown in dotted lines in Fig. 1. All of the burners being rigidly secured to this pipe C, when the pipe is turned in its bearing, the burners are carried with it, as shown in the patent granted to me November 6, 1883,bearing No. 287,911.

As ignorant and careless persons will atl tempt to fill the tank without first extinguish ing the burners,the tank and the supply-pipe are made to move as shown, for the purpose 5 of turning the tank into a position Where it can be filled. In order to leave nothing to the memory or judgment of these careless or ignorant operators, it becomes necessary to provide a mechanism which will'absolutely 6o extinguish every burner before the tank can be moved into a position where it can be lled. For this purpose an endwise-moving rod, D, carrying a number of inclines, E, is provided. This rod D has suitable bearings in the ends of the frame A, and has one of its ends turned upward, as shown in Figs. 1 and 2, so as to ext-end directly across the line of travel of the supply-pipe C when the tank is to be moved into the position shown in dotted lines. The 7o end of this rod D extending across the line of travel of the pipe C serves to lock the pipe, when the burners are open or are free to be' opened, in the vertical position shown in solid lines in Fig. 1, before the tank can be moved into the position shown in dottedlines. This rod D must be moved endwise by hand, as shown in dotted lines in Fig. 2, so as to unlock the pipe O and leave it free to move. Vhen the'rod D is moved endwise, the in- 8o clines E on the screw-threaded arms, to which the inclines are secured, will strike against the lever F of the burners. In case the levers F have not been moved to extinguish the burners, they project across in front of the in- 8 5 clines or the arms to which they are attached, and hence prevent the rod D from being moved endwise. If the outer ends of the levers F have been depressed to close the needle, and by some accident or oversight have 9o not been moved far enough, the inolines will strike against the top of the levers, as shown in Fig. 4., and thus force the outer ends of the levers downward before the rod D has been moved far enough to allow the pipe C to be moved into a position where the tank can be iilled. In case one of the burners has not been quite. extinguished by the movement of the needle, there is just as 'much danger to ers were left at a full blaze. It therefore becomes necessary that the rod D and the inclines connected to it should positively extinguish every burner, and thus leave no posthe operator in filling the tank as if the burnrco sible chance for an accident of any kind. The inclines upon the arms are made vertically adjustable, so that' they can be adjusted to each burner independently in case any of the levers should be out of line. The incline can then be adjusted into that position where it can exert just enough pressure upon the lever to-close the needle, and no more.

I do not limit myself to any detail of construction in making the inclines adjustable in relation to the rod D and the levers, for this may be varied at will. I have made them ad justable in a number of ways, and merely show the screw-thread as one of the simplest forms.

If preferred, the end c of the lever F may be made to extend on beyond the pivot b, and in that case the endwisemoving rod D,with its inclines, will be transferred to the opposite side of the burners to that shown in Fig. 4, so that t-he inclines will strike against the under sides of the ends a, vas shown in dotted lines nl Fig. 5.

The needle-barrel G, through which the needle'II works in the usual manner, is made screw-threaded externally at' its lower end, and screwed upon this barrel is the drip-cup I, which is of the usual construction. Projecting from the under side of this drip-cup, or projecting from the needle-barrel itself, or from any other part of the burner, as shown by dotted lines in Fig. 5, is a suitable supl port, J, in the lower end of which the lever F is pivoted. rlhe needle II is connected to the inner end of the lever F, asshown in Fig.

` 5, while the outer end of the lever extends a vsuitable distance outward, and serves as a means for operating the needle.

The support for the lever is made to project downward from any suitable source, as shown, so that the pivot upon Whichthe lever turns shall be placed between the point at which the lever is connected to the needle at its outer end. Vhen the outer end of the lever is forced downward, either by hand or foot, or the accidental dropping of any object upon it, or the accidental catching of a womans dress, the needle is forced upward, so as toinstantl y extinguish the burner, and thus prevent any possible chance for an accident. Frequently a single burner by some accident will become extinguished While the other burners are in full blast, and the escape of the oil or vapor will cause an explosion. The lever is made to operate, as shown and described, so that any object coming in contact with it from above will extinguish the burners. The endwise movement of the needle through the needle-barrel would soon cause a leakage of the gas were it not that the packing-box L is used. This box L is made screw-threaded internally, and in the box are placed a number of disks of asbestus. As soon as there is the slightest leakage of gas the box is given a slight turn, so as to compress the packing more tightly, and thus stop the leak. Asbestus packingis used, as shown, because it is indestructible by heat. This packing-box L being vertically adjustable upon the needle-barrel, it is necessary that it should be entirely disconnected from the operating-lever. Where the lever is pivoted at the lower end of the needle-barrel, as shown in my patent above referred to, it is impossible to tighten the packing-box, for then the i As gasoline-vapor is very penetrating, it be- I comes absolutelynecessary as a matter of safety to have the needle packed in such a manner that the vapor -or fluid cannot escape around the lower end of the needle. As long as the needle is given an endwise movement it will wear the packing, and hence it is absolutely necessary that the packing-box should be made independent of the lever, so that the packing can be tightened at any moment.

ln the patent granted to me above referred to, the lever is made cam-shaped at the end, and pivoted inthe bearings formed upon the lower end of the packing-box. I am also aware that a lever has been provided with a screwthread, and given arotary longitudinal movement for the purpose of operating the needle, and this I disclaim.

The great advantage gained by pivoting the lever as here shown is that it is pivoted concentrically to the needle, so that it can be turned around with the needle into any desired position, so that no lateral movement of the lever in the use ofthe burner will bring any undue friction upon either the needle or thc packing.

Having thus described my invention, I claiml. The combination, in a vapor-burner, of an endwise-moving valve, a pivoted lever for moving the valve, and a supporter fulcrum for the lever, and which projects down from the burner and supports the lever between its outer free end and its point of connection with the needle-valve, substantially as shown.

2. In a vapor-burner, the combination of the endwise-moving needle and the pivoted lever for moving the same, the lever being pivoted in a suitable bearing or support which projects down from the drip-cup, and which bearing is adapted to move coucentrically to the needle, substantially as described.

3. The combination, in a vapor-burner, of the endwise-:moving needle, the needle-bar rel, the drip-cup which is applied to the needle-barrel, a suitable support which projects down from the drip-cup, the pivoted lever,

and the adjustable packing-box, substantially as specified.

vices for depressing the operatingdevers of the burners when the rod is moved endwise, one of the ends of the rod being mede to act as a lock to prevent the lowering of' the tank untilthe burners have been extinguished, sub- 15 stentiallv as set -forth.

In testimony whereof I affix my signature in presence of two Witnesses.
